Effect of partial replacement of sand by glass powder and steel powder over the properties of M-30 concrete
In the present research, a series of experiments had been performed to compare the use of glass powder and steel powder as partial replacement of sand in different proportions. Concrete mixes are modified by 10%, 15% and 20% and 25% of glass powder and steel powder in replacement. The inclusion of glass powder increases the compressive strength up-to certain proportions. It has also been noted that with the increase in the content of glass powder decreases the slump value or workability. It has also been noted that with the increase in the content of supplementary materials decreases the slump value or workability. Comparatively higher early strength gain (7-days) is obtained with steel powder concrete.

A study on strengthening of soil using stabilized flyash
In the present study, I tried to prove soil stabilization using stabilized flyash. for the stabilization of flyash, we need to improve the flash properties by adding some admixtures. in the present study, we are using lime and sodium silicate as additives to improve the soil properties. Individual geotechnical parameters like grain size distribution, liquid limit, OMC, MDD, Specific gravity and angle of internal friction of Fly ash were determined and then Fly ash was mixed with different proportions of lime (2-15%) and sodium silicate (1-4%). These mixes were tested to obtain the optimum percentage of lime and sodium silicate. The variation in shear parameters like cohesion and angle of shearing resistance was studied by conducting a direct shear test. All the tests were performed after a time period of 3hours starting from the completion of preparation of the sample. Each test was performed for the normal stresses of 0.5kg/cm2, 1kg/cm2, 1.5kg/cm2, 2kg/cm2 and 2.5 kg/cm2. The results are compiled in a graphical form to observe the trends for shear parameters. The results show remarkable improvement in strength characteristics for higher percentages of lime and sodium silicate. The Major challenge on behalf of engineers especially civil engineers is the disposal of industrial waste products and their storage. Nowadays most of the industries reusing the wastes in different areas like civil constructions, treatment of materials and others. This reuse of wastes is essential to overcome the hazardous effects of wastes on the environment. Fly Ash is one of the industrial wastes produced every year throughout the country. Fly ash is a fine powder obtained from burning of coal during the production of electricity. Disposal of Fly ash is a big problem, to minimize the disposal of Fly ash into large land, it was used as a construction material in civil engineering works like building materials embankments, and bricks making etc.

Study on effective utilization of waste materials in the construction of pavements
Research into new and innovative uses of waste material is continually advancing. Many highway agencies, a private organization, and individuals are in the process of a wide variety of studies and research projects concerning the feasibility, environmental suitability, and performance of using recycled products in highway construction. The amount of wastes has increased year by year and the disposal becomes a serious problem. Particularly, the recycling ratio of the plastic wastes in life and industry is very low and many of them have been reclaimed for the reason of unsuitable ones for incineration. It is necessary to utilize the wastes effectively with technical development in each field. Expansive soils are so widely spread that it becomes impossible to avoid them for highway construction to keep the network structure for mobility and accessibility. However, the roads constructed on expansive soils suffer extensive damage and distress resulting in large economic losses running to billions of dollars. As thermal power plants are spatially distributed all over the country, utilization of flyash from these plants for the road construction, not only helps to consume bulk quantities of fly ash solving its disposal problem to a certain extent but also to satisfy the construction requirements. Reinforcement of soils with synthetic fibers is potentially an effective Technique for increasing soil strength. In recent years, this technique has been suggested for a variety of geotechnical applications ranging from retaining structure and earth embankments to subgrade stabilization beneath footings and pavements. Research on a different type of reinforcement and materials has been conducted by several investigators. However, the amount of information available on randomly oriented fiber reinforcement is still limited. Here an attempt is made to the suitability of different types of waste plastics strips and waste tire rubber chips reinforcing with gravel and flash in flexible pavement system on expansive soil subgrade.

Effect of progressive muscular relaxation technique and autogenic relaxation technique on pre competitive state anxiety and self-confidence in athletes
Pre-test and Post-test control group design. Participants: 45 subjects were selected on the basis of their CSAI-2R score, they were randomly allocated to one of the three groups. Group 1 (progressive muscular relaxation) group 2 (autogenic relaxation) group 3 (control). Intervention: Progressive muscular relaxation technique and Autogenic relaxation technique for 15-20 minutes. Main outcome measures include somatic anxiety, cognitive anxiety, self-confidence. There was a significant reduction in somatic anxiety & cognitive anxiety and improved self-confidence found in both groups 1& 2 than group 3 (p < 0.05) whereas no significant difference observed in group 1 and group 2. From the result of the study it was concluded that relaxation technique is an effective intervention for reducing pre competitive state anxiety and improving self-confidence in athletes. As both progressive muscular relaxation & autogenic relaxation technique were significantly effective in reducing competitive state anxiety and improving self-confidence than the control group.

Detecting distributed DOS attacks using Multivariate Correlation Analysis
This paper focuses on identification of DDoS using MCA technique. The intention of this paper is to identify DDoS attack. For that MCA technique use. MCA technique is useful for identification of DDoS attack. MCA is for accurate network of packet traffic. MCA technique uses the anomaly detection approach and triangle area base approach. Anomaly based approach is for finding known and unknown type of attack. Triangle area base approach is for improving the speed of MCA process. In this to test real world data for false positive rate.

The physics of Magnetic Resonance Imaging
MRI is an acronym for Magnetic Resonance Imaging. MRI is used in radiology and it is one of the scanning technologies where magnetism, radio waves, and a computer are used to take the total image of the body structures. The chief advantage of the MRI is to give clear images of the soft-tissue structure where other imaging techniques fail to give without any effect to the patient.MRI is based on the interaction of magnetic properties of hydrogen with both a large external magnetic field and radio waves, which send signals to the body and then receive signals back. These returning signals are converted into images by a computer attached to the scanner. Imaging of any part of the body can be obtained in any plane. This Article gives a brief idea about the history, construction, working principle of MRI which includes Nuclear spin, Larmour,s frequency, T1 and T2 relaxation and T1 and T2 weighted images.
